Impact of a Multifaceted Intervention on Antibiotic Prescribing for Cystitis and Asymptomatic Bacteriuria in 23 Community Hospital Emergency Departments.

Background: Urinary tract infections (UTIs) are over-diagnosed and over-treated in the emergency department (ED) leading to unnecessary antibiotic exposure and avoidable side effects. However, data describing effective large-scale antimicrobial stewardship program (ASP) interventions to improve UTI and asymptomatic bacteriuria (ASB) management in the ED are lacking. Methods: We implemented a multifaceted intervention across 23 community hospital EDs in Utah and Idaho consisting of in-person education for ED prescribers, updated electronic order sets, and implementation/dissemination of UTI guidelines for our healthcare system. We compared ED UTI antibiotic prescribing in 2021 (post-intervention) to baseline data from 2017 (pre-intervention). The primary outcomes were the percent of cystitis patients prescribed fluoroquinolones or prolonged antibiotic durations (>7 days). Secondary outcomes included the percent of patients treated for UTI who met ASB criteria, and 14-day UTI-related readmissions. Results: There was a significant decrease in prolonged treatment duration for cystitis (29% vs 12%, P < .01) and treatment of cystitis with a fluoroquinolone (32% vs 7%, P < .01). The percent of patients treated for UTI who met ASB criteria did not change following the intervention (28% pre-intervention versus 29% post-intervention, P = .97). A subgroup analysis indicated that ASB prescriptions were highly variable by facility (range 11%-53%) and provider (range 0%-71%) and were driven by a few high prescribers. Conclusions: The intervention was associated with improved antibiotic selection and duration for cystitis, but future interventions to improve urine testing and provide individualized prescriber feedback are likely needed to improve ASB prescribing practice.

Effect of tele-COVID rounds and a tele-stewardship intervention on antibiotic use in COVID-19 patients admitted to 17 small community hospitals.

Antibiotic stewardship interventions are urgently needed to reduce antibiotic overuse in hospitalized COVID-19 patients, particularly in small community hospitals (SCHs), who often lack access to infectious diseases (ID) and stewardship resources. We implemented multidisciplinary tele-COVID rounds plus tele-antibiotic stewardship surveillance in 17 SCHs to standardize COVID management and evaluate concurrent antibiotics for discontinuation. Antibiotic use was compared in the 4 months preintervention versus 10 months postintervention. Interrupted time-series analysis demonstrated an immediate decrease in antibiotic use by 339 days of therapy/1000 COVID-19 patient days (p < .001), and an estimated 5258 antibiotic days avoided during the postintervention period. Thirty-day mortality was not significantly different, and a significant reduction in transfers was observed following the intervention (23.3% vs. 7.8%, p < .001). A novel tele-ID and tele-stewardship intervention significantly decreased antibiotic use and transfers among COVID-19 patients at 17 SCHs, demonstrating that telehealth is a feasible way to provide ID expertise in community and rural settings.

A Fully Integrated Infectious Diseases and Antimicrobial Stewardship Telehealth Service Improves Staphylococcus aureus Bacteremia Bundle Adherence and Outcomes in 16 Small Community Hospitals.

Background: Infectious diseases (ID) and antimicrobial stewardship (AS) improve Staphylococcus aureus bacteremia (SAB) outcomes. However, many small community hospitals (SCHs) lack on-site access to these services, and it is not known if ID telehealth (IDt) offers the same benefit for SAB. We evaluated the impact of an integrated IDt service on SAB outcomes in 16 SCHs. Methods: An IDt service offering IDt physician consultation plus IDt pharmacist surveillance was implemented in October 2016. Patients treated for SAB in 16 SCHs between January 2009 and August 2019 were identified for review. We compared SAB bundle adherence and outcomes between patients with and without an IDt consult (IDt group and control group, respectively). Results: A total of 423 patients met inclusion criteria: 157 in the IDt group and 266 in the control group. Baseline characteristics were similar between groups. Among patients completing their admission at an SCH, IDt consultation increased SAB bundle adherence (79% vs 23%; odds ratio [OR], 16.9; 95% CI, 9.2-31.0). Thirty-day mortality and 90-day SAB recurrence favored the IDt group, but the differences were not statistically significant (5% vs 9%; P = .2; and 2% vs 6%; P = .09; respectively). IDt consultation significantly decreased 30-day SAB-related readmissions (9% vs 17%; P = .045) and increased length of stay (median [IQR], 5 [5-8] days vs 5 [3-7] days; P = .04). In a subgroup of SAB patients with a controllable source, IDt appeared to have a mortality benefit (2% vs 9%; OR, 0.12; 95% CI, 0.01-0.98). Conclusions: An integrated ID/AS telehealth service improved SAB management and outcomes at 16 SCHs. These findings provide important insights for other IDt programs.

A Novel Program to Provide Drug Recovery Assistance and Outpatient Parenteral Antibiotic Therapy in People Who Inject Drugs.

BACKGROUND: Safe hospital discharge on parenteral antibiotic therapy is challenging for people who inject drugs (PWID) admitted with serious bacterial infections (SBI). We describe a Comprehensive Care of Drug Addiction and Infection (CCDAI) program involving a partnership between Intermountain Healthcare hospitals and a detoxification facility (DF) to provide simultaneous drug recovery assistance and parenteral antibiotic therapy (DRA-OPAT). METHODS: The CCDAI program was evaluated using a pre-/poststudy design. We compared outcomes in PWID hospitalized with SBI during a 1-year postimplementation period (2018) with similar patients from a historical control period (2017), identified by propensity modeling and manual review. RESULTS: Eighty-seven patients were candidates for the CCDAI program in the implementation period. Thirty-five participants (40.2%) enrolled in DRA-OPAT and discharged to the DF; 16 (45.7%) completed the full outpatient parenteral antibiotic therapy (OPAT) duration. Fifty-one patients with similar characteristics were identified as a preimplementation control group. Median length of stay (LOS) was reduced from 22.9 days (interquartile interval [IQI], 9.8-42.7) to 10.6 days (IQI, 6-17.4) after program implementation (P < .0001). Total median cost decreased from $39 220.90 (IQI, $23 300.71-$82 506.66) preimplementation to $27 592.39 (IQI, $18 509.45-$48 369.11) postimplementation (P < .0001). Ninety-day readmission rates were similar (23.5% vs 24.1%; P = .8). At 1-year follow-up, all-cause mortality was 7.1% in the preimplementation group versus 1.2% postimplementation (P = .06). CONCLUSIONS: Partnerships between hospitals and community resources hold promise for providing resource-efficient OPAT and drug recovery assistance. We observed significant reductions in LOS and cost without increases in readmission rates; 1-year mortality may have been improved. Further study is needed to optimize benefits of the program.

Implementation of an Infectious Diseases Telehealth Consultation and Antibiotic Stewardship Program for 16 Small Community Hospitals.

BACKGROUND: Telehealth improves access to infectious diseases (ID) and antibiotic stewardship (AS) services in small community hospitals (SCHs), but the optimal model has not been defined. We describe implementation and impact of an integrated ID telehealth (IDt) service for 16 SCHs in the Intermountain Healthcare system. METHODS: The Intermountain IDt service included a 24-hour advice line, eConsults, telemedicine consultations (TCs), daily AS surveillance, long-term AS program (ASP) support by an IDt pharmacist, and a monthly telementoring webinar. We evaluated program measures from November 2016 through April 2018. RESULTS: A total of 2487 IDt physician interactions with SCHs were recorded: 859 phone calls (35% of interactions), 761 eConsults (30%), and 867 TCs (35%). Of 1628 eConsults and TCs, 1400 (86%) were SCH provider requests, while 228 (14%) were IDt pharmacist generated. Six SCHs accounted for >95% of interactions. Median consultation times for each initial telehealth interaction type were 5 (interquartile range [IQR], 5-10) minutes for phone calls, 20 (IQR, 15-25) minutes for eConsults, and 50 (IQR, 35-60) minutes for TCs. Thirty-two percent of consults led to in-person ID clinic follow-up. Bacteremia was the most common reason for consultation (764/2487 [31%]) and Staphylococcus aureus the most common organism identified. ASPs were established at 16 facilities. Daily AS surveillance led to 2229 SCH pharmacist and 1305 IDt pharmacist recommendations. Eight projects were completed with IDt pharmacist support, leading to significant reductions in meropenem, vancomycin, and fluoroquinolone use. CONCLUSIONS: An integrated IDt model led to collaborative ID/ASP interventions and improvements in antibiotic use at 16 SCHs. These findings provide insight into clinical and logistical considerations for IDt program implementation.

Antibiotic prescribing for adult bacteriuria and pyuria in community hospital emergency departments.

OBJECTIVE: To describe emergency department (ED) antibiotic prescribing for urinary tract infections (UTIs) and asymptomatic bacteriuria (ASB) and to identify improvement opportunities. METHODS: Patients treated for UTI in 16 community hospital EDs were reviewed to identify prescribing that was unnecessary (any treatment for ASB, duration >7 days for cystitis or >14 days for pyelonephritis) or suboptimal [ineffective antibiotics (nitrofurantoin/fosfomycin) or duration <7 days for pyelonephritis]. Duration criteria were based on recommendations for complicated UTI since criteria for uncomplicated UTI were not reviewed. 14-day repeat ED visits were evaluated. RESULTS: Of 250,788 ED visits, UTI was diagnosed in 13,466 patients (5%), and 1427 of these (11%) were manually reviewed. 286/1427 [20%, 95% CI: 18-22%] met criteria for ASB and received 2068 unnecessary antibiotic days [mean (±SD) 7 (2) days]. Mean treatment duration was 7 (2) days for cystitis and 9 (2) days for pyelonephritis. Of 446 patients with cystitis, 128 (29%) were prescribed >7 days (total 396 unnecessary). Of 422 pyelonephritis patients, 0 (0%) were prescribed >14 days, 20 (5%) were prescribed <7 days, and 9 (2%) were given ineffective antibiotics. Overall, prescribing was unnecessary or suboptimal in 443/1427 [31%, 95% CI: 29-33%] resulting in 2464/11,192 (22%) unnecessary antibiotic days and 8 (0.5%) preventable ED visits. CONCLUSIONS: Among reviewed patients, poor UTI prescribing in 16 EDs resulted in unnecessary antibiotic days and preventable readmissions. Key areas for improvement include non-treatment of ASB and shorter durations for cystitis.

Multifocal osteomyelitis due to Mycobacterium szulgai in a patient with chronic lymphocytic leukemia.

Mycobacterium szulgai is a pathogenic organism that most frequently causes pulmonary infection and may rarely result in disseminated disease in immunocompromised individuals. We report a case of multifocal osteomyelitis and cutaneous lesions due to M. szulgai in a patient with chronic lymphocytic leukemia. The successful treatment of multifocal osteomyelitis was accomplished using isoniazid, rifampin, and ethambutol.

Development of functional diarrhea, constipation, irritable bowel syndrome, and dyspepsia during and after traveling outside the USA.

BACKGROUND: Persistent gastrointestinal (GI) symptoms after travel abroad may be common. It remains unclear how often subjects who developed new GI symptoms while abroad have persistent symptoms on return. The objective of this retrospective study was to evaluate the prevalence of persistent GI symptoms in a healthy cohort of travelers. METHODS: One hundred and eight consecutive patients, mostly returned missionaries, attending the University of Utah International Travel Clinic for any reason (but mostly GI symptoms) had data recorded about their bowel habits before, during, and after travel abroad. All subjects had standard hematological, biochemical, and microbiological tests to exclude known causes of their symptoms. Endoscopic procedures were performed when considered necessary by the treating physician. Diarrhea, constipation, irritable bowel syndrome (IBS), bloating, and dyspepsia were defined according to the Rome II Criteria. RESULTS: Eighty three (82% men and 18% women, median age 21 years) completed the survey with 68 subjects completing the questionnaire about bowel habits before and during travel. Among the respondents, 55 (82.1%) did not have any symptoms before travel. During travel, 41 (63%) developed new onset diarrhea; 6 (9%) developed constipation; 16 (24%) IBS, 29 (45%) bloating; and 11 (16%) dyspepsia. Of those who developed symptoms during travel, 27 (68%) had persistent diarrhea, 3 (50%) had persistent constipation, 10 (63%) had persistent IBS, 12 (43%) had persistent bloating and 8 (73%) had persistent dyspepsia. The presence of bowel symptoms during and after travel was not associated with age, gender, travel destination, or duration of travel. CONCLUSIONS: This study suggests that new onset of diarrhea, IBS, constipation, and dyspepsia are common among subjects traveling abroad. Gastrointestinal symptoms that develop during travel abroad usually persist on return.
